SPRING-VEHICLE.

SPECIFICATION forming part of Letters Patent No. 288,634, dated November 20, 1883,

Application filed July 30, 1883. (No'modeh) To all whom it may concern Be it known that I, ADOLPH E. HERMAN, a citizen of Ravenna, in the county of Portage and State, of Ohio, have invented a new and useful Improvement in Spring -Vehicles, of which the following is a specification.

The principal object of my invention is to dispense with a reach and equalize the vertical movement of the box in all its parts, and prevent tilting when the weight or downward pressure is applied at any part of the box.

In the drawings forminga part of this specification, Figure l is a side elevation, and Fig. 2 is a view of the bottom, of the vehicle.

The front end of box I) is attached to fifthwheel w, and the rear end is connected by rods lwith block 12 on spring (1. Spring it turns with the front axle, w, in clip a. The location of fifth-wheel w may be changed, if preferred, by placing it between axle m and spring d, and in that case the spring will not turn with the axle.

Rod 8 is hinged to clip a at one end and to link 8 at the other end. Link 8 ishinged to lug 8 attached to the bottom of box 21. Rod 12 is hinged to link 8 at one end, and to a crank or wrist, n, on rod 9. Rod g has an oscillating movement, and is supported by'staples n n in the bottom of box b. Rod a is hinged at one end to crank or wrist n and at the other to rod 6. The upper end of rod 6 is hinged to luge, at the bottom of box b, and its lower end is hinged to one end of rod t. The other end of rod 11 is hinged to the rear axle, .00. extends across or nearly across the bottom of box I), and is formed with short cranks c c at its ends, to which rods 0 c are hinged. The other ends of rods 0 a are hinged to the rear axle, as.

The rods hereinabove described are relatively so arranged that all of them are moved and springs d d are compressed whenever a sufficient weight or downward pressure is brought to bear on any part of box b. To illustrate, if the whole weight be on the front end of box b, it forces down andback rods 8, n, and a, turning crank n back and cranks 0 c for- Rodgward, and forcingback and down rods 6 andt and the hind part of box b. The relative positions of the various parts will then be as in- 0 dicated by'dotted lines in Fig. 2. The same result will follow if the weight be on the hind end of the vehicle. Rods e and t will then be forced down and back, rods a and a will be drawn back, thus forcing down rod 8, link 8, and the forward end of box 12. If the weight be all on either side of box I), the box will not tilt, but both sides of it will be forced down to substantially an equal extent. This effect is produced through rod 9 in this way: When either side of box I) is pressed down, the 'inclined rod 0 on that side will turn forward cranks c c, at both sides of box I), and also turn backward crank or wrist n, thereby drawing back rods n, a, e, and i, and forcing down rod. s and the box. Bods s, n, a, e, andz' are arranged centrally of the bottom of box b, be-

tween axles x m, in order to have an equal effect on both sides of the box.

In a two-wheeled vehicle rods 01. s and link s may be dispensed with. As cross-rod g and rods 0 c are mainly to prevent lateral tilting of the box, they may be removed, and a single hinged rod-connecting link, 8, with rod 6', may be used in place of the two rods n and a. for the purpose of bracing the axles and equalizing the compression of the two springs.

I claim as my invention- 1. The hinged rods 11 e a, c and the cross-rod having cranks c n, in combination with axle w, spring (2, and box I), substantially as described.

2. The box, axles, and springs of a vehicle, in combination with the hinged rods i e, connected by one or more hinged rods with link s and rod 8, substantially as described.

3. A vehicle-box, axles, and springs, in combination with hinged rods s n a e z 0 c, cross-rod 9, having cranks c c n, and link 8, substantially as described.
